SAGA uses an innovative collectible revenue model first implemented by the THQ studio Genetic Anomalies in 1997 and now seen in over 120 online collectible games, such as the upcoming EA collectible RTS BattleForge.SAGA has no subscription fees. Players pay as little or as much as they decide, by purchasing ‘booster packs’ of random troops and spells, which are traded and customized to create the strategic army of choice for each player.
